I think at times the atheistic and agnostic stances falsely believe they have risen above having to give an accounting for the reality around us. I am not so certain any of us are off the hook from the difficult questions of life.
“Prove that God exists.”
That’s the typical request to which it may be helpful to have our atheistic and agnostic friends work on a similar problem while we are thinking that one through. Prove that God does not exist. Neither of us live apart from faith.
“How do you know truth?”
That may be the question we are forgetting to have our atheistic and agnostic friends work through. As a Christian, Jesus is my standard of overarching truth. More specifically what the Bible has captured and retained for us regarding Jesus. My atheist and agnostic friends have yet to come up with a standard of truth outside of themselves.
If you are your own truth standard, then so is Joe, Bobby, Chris, Susan, and every other human, and at the moment you say truth is subjective, you have just used an objective overarching truth to do that. Which denies the atheist and agnostics entire system of knowing things. Can you keep making truth claims and not actually believe in truth?
I have agnostic and atheistic friends that are some of the best folks I know, but I am not so convinced that I am the only one with some explaining to do…
“My goal is that they may be encouraged in heart and united in love, so that they may have the full riches of complete understanding, in order that they may know the mystery of God, namely, Christ, 3 in whom are hidden all the treasures of wisdom and knowledge.” Colossians 2:2-3
